Human rights groups have condemned international construction firms for their role in the destruction of Palestinian villages including Khan al-Ahmar, which is set to be razed in the coming days.

Photographs, video and social media posts show vehicles and equipment that have been sold to the Israeli army by Caterpillar, JCB and LiuGong being used in the demolition of Palestinian homes. All three companies have declined or failed to respond to MEE's requests for comment.

Vehicles and equipment sold to the Israeli army by Caterpillar, JCB and LiuGong have been used in the demolition of Palestinian homes

In early September, the Israeli High Court of Justice rejected several last-ditch petitions filed by Khan al-Ahmar's residents and said that authorities could raze the homes from 12 September onwards.

Amnesty International described the High Court's decision as sanctioning a "war crime" while UK-based NGO War on Want condemned the companies, which it says profit from sales of the equipment to the Israeli government.

War on Want's Senior Campaigns Officer, Ryvka Barnard added that video and images incriminated Caterpillar, JCB, and Liugong for their role in Palestinian house demolitions.

"We've seen photographic and video evidence of equipment from JCB and Liugong, for example, being used by the Israeli army and waiting to go into places like Khan al-Ahmar," Barnard told MEE.

Activists have been exposing the complicity of companies like JCB and Caterpillar for many years, but the companies tend to respond in the typical manner of saying the human rights violations sadden them, but that they have no power over their equipment is used."

Khan al-Ahmar is located between the Israeli settlements of Maale Adumim and Kfar Adumim in the occupied West Bank, and has been a home for Bedouin since the 1950s. It has been at risk of demolition since 2010 after Israeli authorities accused the estimated 200 residents of illegal construction.

Residents have rejected a government offer to rehouse them to West Jahalin, near the Palestinian community of Abu Dis, saying that the new site is adjacent to a landfill. Rights advocates say that a forcible transfer of the residents would violate the international laws that apply to occupied territories.

Caterpillar (CAT)

The US-based heavy equipment company has long been the target of boycott campaigns for its sale of bulldozers to the Israeli army.

In July, villagers who spottedthe CAT-branded heavy drilling equipment outside Khan al-Ahmar feared that it would lead to the construction of a new road for the nearby Israeli settlements of Maale Adumim and Kfar Adumim.

CAT bulldozers have been used previously by the Israeli army to demolish homes across the occupied Palestinian territories, including the D9 bulldozer, which killed American activist Rachel Corrie in 2003.

In 2012, CAT was removed from the index of "socially responsible" companies put together by American investment support firm MSCI Inc; it cited concerns about CAT bulldozers being used by Israel in controversial operations.

CAT said that it "does not equip tractors with armour or sell directly to the Israeli military but through the US government. And it cannot monitor the use of every piece of its equipment around the world".

The company did not respond to calls for comment when asked by MEE about the presence of its equipment in Khan al-Ahmar.

JCB

The British-based company is famed for its yellow bulldozers. Israel has used its equipment in occupied East Jerusalem, Gaza, the Jordan Valley and across the West Bank.

In the past, its vehicles have been used by the Israeli government to build illegal Israeli settlements and by the army to destroy Palestinian homes, mosques and agricultural areas.

In 2012 JCB's equipment was used to demolish homes in Silwan, a Palestinian neighbourhood in East Jerusalem. It dominates the Israeli market with a 65 percent market share of all excavators and a 90 percent market share of commonly used loading vehicles.

LiuGong

Like JCB and CAT, the company supplies bulldozers and other types of heavy construction equipment. Operating out of the Jebel Ali Free Zone in Dubai, it opened its Middle East office in 2011.

Footage showed LiuGong bulldozers being used to dismantle Bedouin homes in early July,while other Palestinian activists sat on top of the diggers in a bid to stop them destroying Khan al-Ahmar.

The use of LiuGong bulldozers by the Israeli army represents the growing Chinese presence in the country and across the Middle East, as European and American based construction companies face growing pressure to stop trading with Israel.

LiuGong did not respond to requests for comments at the time of writing.
